Two days later Cassidy Freeman, who appeared in Smallville, also accused Piven of sexual assault.

"I know what you did and attempted to do to me when I was far too young," Freeman wrote on Instagram.

"Do you feel powerful? With your lawyers and your networks and your die hard man-fans who call your victims bimbos? Or do you know, in your rotten gut, that you will have to lie for the rest of your life? I hope from now on, you keep it in your pants and you never get to do it again."

A third woman, advertising executive Tiffany Bacon Scourby, told People that Piven assaulted her back in 2003 after inviting her back to his hotel.

"We were talking for about five minutes and he said he was waiting for his [publicist] to come with us," she told the magazine.

"He jumped on top of me. I tried to push him off and he forced me to the ground."

"Let me begin by saying that the accusations against me are absolutely false and completely fabricated," he wrote.

"I would never force myself on a woman. Period. I have offered to take a polygraph to support my innocence. I keep asking myself, 'How does one prove something didn't happen?'

"What I am not able to do is speculate as to the motivations of these women. As a human being I feel compassion for the victims of such acts, but I am perplexed as to the misdirection of anger with false accusations against me and hope they do not detract from the stories that should be heard.

"We seem to be entering dark times - allegations are being printed as facts and lives are being put in jeopardy without a hearing, due process or evidence. I hope we can give people the benefit of a doubt before we rush to judgment.

"Continuing to tear each other down and destroy careers based on mere allegations is not productive on any level. I hope we can use this moment to begin a constructive dialogue on these issues, which are real and need to be addressed."

Piven currently stars in the TV show Wisdom of the Crowd which will air on Network Ten in 2018.
